Techniques for Mapping
Drawing or sketching a map can be the most effective and simplest form of obtaining quick and easy map data. This can be done by simply looking around one self or performing a more detailed survey of the area. A transect is an effective technique for obtaining data for a cross-sectional map. Also multiple transects can be combined to supply data for other aerial, topographic, or sketched maps. Interviewing others is another effective way to obtain mapping information such as borders, land use, land cover, ownership, and other features. One must be very careful when obtaining such information from others as it can easily be biased data. All second-hand data should be verified with at least one other source.
